Log: Quell false positives in svc_vc_create and svc_vc_create_conn with cd and xprt Both cd and xprt will be non-NULL after their respective malloc(9) wrappers are called (mem_alloc and svc_xprt_alloc, which calls mem_alloc) as mem_alloc always gets called with M_WAITOK|M_ZERO today. Thus, testing for them being non-NULL is incorrect -- it misleads Coverity and it misleads the reader. Remove some unnecessary NULL initializations as a follow up to help solidify the fact that these pointers will be initialized properly in sys/rpc/.. with the interfaces the way they are currently.
